What do the differences mean?

What is compared
The tool requests the same record from five public resolvers and shows the value, TTL and DNSSEC validation for each answer.
Different answers
Differences often follow a recent change or geo-aware DNS. Sometimes nameservers are serving different zone data.
No answer
NXDOMAIN: name not found. No record: type missing. SERVFAIL: query failed. The comparison remains a snapshot.
